Till now experts believed that nerve fibers in the skin were responsible for detecting stimuli like blows and pricks. Now a team in Sweden have announced the discovery of a mesh-like organ within the skin, named nociceptive glio-neural complex.
These Glial cells are surrounded by hair-like structures that are thought to be sensitive to stimuli. Research were able to find these cells in mice. When they were blocked, the mice had reduced sensations of pain.
Researchers hope this new discovery will help experts understand chronic pain and develop better treatments. Lead professor Patrik Ernfors said ” Our study shows sensitivity to pain does not occur only in the skin’s nerve fibers, but also in this recently discovered pain-sensitive organ… The discovery changes our understanding of the cellular mechanisms of physical sensation and it may be of significance in the understanding of chronic pain.”
